INTERNAL-COMBUSTION ENGINE,

Specification of Letters Patent, I Patented May 30, 1916,

Application filed January 2, 1915. Serial No. 57.

To all whom it may concern Be it known that I, CLARENCE D. MILLER, acitizen of the United States, residing at the city of Philadelphia, inthe county. of Phlladelphia and State of Pennsylvania, have inventedcertain new and useful Improvements in Internal-Combustion Engines, ofwhich the following ,is a specification.

My invention relates to that class of internal combustion engines knownas a rotary valve type, in which puppet valves are not used as I use acircular sleeve or ring in place thereof withan opening or port, thesleeve usually being slit or cut and when out it is usually at or nearthe said opening or port. This form of motor. and valve'is more simplein construction, cheaper to manufacture, and has less parts than othertypes of motors which use the puppet or sleeve valves.

The principal objects of the present invention are to improve internalcombustion engines, more particularly in respect to the valves and theiraccessories; to reduce the number and simplify the construction of thevalve parts and so to provide a, comparatively inexpensive internalcombustion engine; to provide for holding comparatively high compressionand thus elfectingeconomy in operation; to so construct and combine theparts that they will be quiet in operation, will not be interfered withbydeposition of carbon and will require comparatively few repairs which,as well as adjustments, can be readily made; and to avoid the use ofparts which are expensive to make and require re-grinding at intervalsto maintain. them in proper condition.

One object of my invention includes an internal combustion engine havinga sleeve or ring or sleeves or, rings mounted upon a hollow stud orshaft with a collar either integral with said stud or shaft, or boltedor screwed to said stud or shaft. In referring to'the ring or sleeve Ido not confine myself shaft being hollow, with an opening or port,

to allow an incoming charge of gas or vapor to enter to produce thenecessary explosion,

erly and thus allow the expulsion of the ex with means for permittingthe gas or vapor 55. after it has been exploded to' be expelled orpassed out through the opening or port.

Another object of my invention covers the use of a ring or sleeve, beingsplit as described, and in which the natural expansion 0 and contractionof the metal has the effect of opening or closing the valve. to produceand retain the described and requisite compression necessary in aninternal combustion engine.

Another object of my invention is to have the sleeve or ring so mountedon the stud or shaft that when the gas or vapor is admitted through theopening or port, the sleeve or ringwill partially rotate or revolve withthe stud or shaft in such a-manner, that when the charge of gas or vaporis admitted, the I sleeve will rotate or partially revolveprophaust gasor vapor after explosion.

Another object of my invention'is to have the sleeve or ring on the studor shaft mounted in such a manner that the opening or port registers sothat the two ports, namely the sleeve port opening and the port. soopening in the stud work in unison with the opening or port in said studor shaft.

Another object of my invention is to have the stud or shaft with theopening or port have a collar bearing upon a thrust bearing over orunder said collar, so that the partial rotary motion may be accomplished.without undue strain or wear on any of the parts. I

' Another object of my invention is to have the stud o'r shaft with theopening or port havmg a collar, and having means where- 'by a'gear orgears-may be attached to or fastened on the said stud or shaft, which 4gear or gears are in turn connected with a shaft running at or aboutright angle thereto, the said latter shaft having gears which mesh withthose on the stud or shaft for the purpose of proper timing of therevolutions and explosions of the. motor.

Another object of my invention is to have the sleeve or ring with theopening or port, the stud or shaft, the collar, and the gear or gears insuch position that a cap or housing may be placed over the gearswithoutv dis- 105 turbing, changing, or interfering with the alinementorproper working of the parts of the internal combustion engine, therebya after described and specifically combined as fnot running.

producing a new, useful, and cheap method of manufacturing an engine ofthe type de-. scribed, that is accessible in all its working partsmerely-by removing a cap or housing, either when the engine is inoperation or My invention also covers the construction of an internalcombustion engine as above described, but is not limited to the use ofone sleeve or ring, but to any number that maybe desired to accomplishthe same or' equivalentv purpose.

My invention also includes various im- I provements in the constructionof internal combustion engines and in the parts herereferred to, and Ido'not limit myself in either my specifications or claims to the Inthedrawings 1,is a valve casing proparticular forms of the parts describedand illustrated, but other forms producing the same or equivalentresults are covered by my y of an internal combustion engine embodying i35 features of the invention. Fig. 2, isa sec:

tional view drawn to an enlarged scale and illustrating features of theinvention. Fig. 3, is a perspective view of one of the parts detached,and Fig. 4:, is a transverse sectional view of Fig. 2.

vided with a cylindrical opening that extends clear through it andconstitutes a valve seat and with an intake port 2, and an exhaust port3. The valve seat is pro vided at the end thereof where it communicateswith the cylinder 4:, and a contracted shoulder 5. At the top of thevalve seat there is an enlarged shoulder 6.

7 is a stud provided with a collar 8, and with a hollow valve body 9,having a port 10,'formed through the wall thereof. The elements 7, 8,and 9, may be made integral or they may be suitably connected togetherso as to constitute in efi'ect one piece. The rim of the valve 9, nearone-end has a bearing in the portion 11, of the valve seat beyond theshoulder 5, and the collar 8, has a bearing in the valve seat inside ofthe shoulder 6. p

12, is a bearing ring through which the stud 7 passes and which isseated upon the shoulder 6, and which is provided with an extension thatis seated on the collar 8.

13, isa' locking ring that encircles a boss aieaeee on the bearing ringand has screw and thread engagement with the valve seat and serves tohold the bearing ring.

14, is a sleeve split as at 15, and provided with a port 16, alined withthe port 10. This split sleeve '14, is arranged between the valve 9, andthe wall of the valve seat and extends from the shoulder 5, to the innerface of the collar 8. This split sleeve is contracted when it is put inplace and hence it tends by its resiliency or springiness to expand andhug the inner face of the valve seat. A pin 17, is shown as an exampleof a means for keeping the ports 10 and 16, opposite each other. is aworm gear 18. The drive shaft 19, is provided with a number of worms 20,one for the worm wheel of each valve, and the valve bodies 9, of thedifi'erent cylinders L, are so set with regard to their ports 10, andthe inlets and exhausts that the operation of the various pistons andcylinders are properly timed. The shaft 19, is shown as driven from thecrank shaft 22, by means of a shaft 23, and gearing 24:.

25, is an oil feeder. The valve casing is provided with walls 26, whichtogether with the removable cover 27, constitute an oil receptacle inwhich the valves and their accessories are arranged. When the cover 27,is removed, access may be readily had to the valves and their parts.

The split sleeve 14, is contracted when it is arranged in the valvecasing and it tends to open so that it hugs the curved wall of the valvechamber in which it is arranged. The valve chamber is subject toexpansion and contraction under the" heat to which it is exposed but thesplit sleeve by expanding and contracting compensates for this while atthe same time properly holding the compression'in the cylinder so thatthe valves can be easily rotated and do not tend to stick or 3' am. Thecompression in the cylinder is not only held by the sleeve but also bythe collar 8, in cooperation with the bearing ring 12.

It will be obvious to those skilled in the art to which theinventionrelates that modifications may be made indetails of construction andarrangement without departing from the spirit of the invention, hencethe latter is not limited as to those matters or in any way further thanthe prior state of the art and the appended claims may require.
